WINDOW-SCREEN.

SPECIFICATION forming part of LettersrPatent No. 709,346, datedSeptember 16, 1902.

Application filed July 3, 190i. Serial No. 67,050. (No model.) i

To @ZZ whom, t may concern,.-

Beit known that I, HENRY DrMILLS, a citizen of the United States,residing at Fishs Eddy, in the county of Delaware and State of NewYork,haveinvented new and useful Improvements in Window-Screens, of which thefollowing is a specification.

This invention relates to improvements in window-screens for houses,coaches, dac., and

Io has for its object to providea screen attach-A ment for sasheswhereby when the Asash is` Y opened a screen will be automatically drawnout to cover or close the space left vacant by the sash.

x5 A further object of the invention is to provide improved meanswhereby the screen is detachably secured to the sash.

With these and other objects in view the invention consists of certainnovel features of zo construction, combination, and arrangement ofparts, as will be hereinafter more fully described, particularly pointedout in the appended claims, and illustrated in the accompanyingdrawings, in whichi Figure lis a fragmentary front elevation of awindow-sash casing and screen embodying my invention. Fig. 2 is avertical central section, on an enlarged scale, through the sash andcasing shown in Fig. l. Fig. 3 is a 3o detail perspective View of 'thesash, illustrat- 4o the sash is mounted.

Mounted in a chamber or recess 4 in the sill 2 is a spring-actuatedshaft or roller 5, to which is secured one end of a flexible screen 6,which is adapted to wind thereon. This screen is adapted to fit and movewithin a slot '7, formed in the upper rail of the sill 2, and isprovided at its opposite or free end with a connecting device consistingof an anguiar or substantially L-shaped plate 8, to

5o the vertical flange of which the said free end of the screen isattached. This plate is formed in the upper portion of its verticalflange with an opening 9 for the reception of a headed operating-pinl0,carried by a bail 11. The bail ll is constructed of a single pieceofiresilient material having its ends bent at right angles andperforated for the reception of screws or other suitable devices tosecure the same to the under side of the bottom rail of the bail, whichis recessed, permitting the bail to lie 6o flush when the window is inits closed position. The pin l0 has a slight outward and upwardcurvature, so as to project beyond the face of the sash and to permitthe horizontal ange of the angular plate 8 to be clamped against 65 theunder side of the bottom rail of the sash by the bail l1. The bail beingcomposed of resilient material and secured at its ends will have aslight spring action, whereby the head of the pin, which forms a knob oriinger- 7o piece, may be grasped and the bail bent downwardly to asufficient extent to allow for the engagement and disengagement of theplate 8 with and from said bail, thereby permitting of the screen beingattached to and detached from the sash at will. When the screen is outof use and when the sash is closed, the vertical iiange of the plate 8occupies the slot 7, while the horizontal flange of said plate seatswithin a communicating 8o recess or countersink 12, formed in the upperface of the top rail of the sill 2, so that said flange will lie Hushwith the sill and allow the sash to close down to its fullest extent.When the sash is elevated, the screen 6 is 85 drawn outward to close aspace or opening left thereby, and when the sash is closed the screenautomatically winds upon the shaft or roller 5. The spring-actuatedshaft or roller maintains the screen taut, no matter in what 9o positionthe sash is adjusted, whether the sash be fully or only partly opened,as will be readily understood.

It is apparent from the above description that the plate 8 may beattached to any form 95 of screen which is capable of sliding in and outof a recess in a sill, andtherefore I do not wish it to be understoodthat I limit myself to a screen mounted upon a spring-actuated roller.

From the foregoing description, taken in connection with theaccompanying drawings,

IOO

the construction, mode of operation, and advantages of the inventionwill be readily un derstood Without a further extended description.

Having thus fully described my invention, what I claimvas new, anddesire to secure by Letters Pat-ent, is-

1. The combination `with i a Window Sash and frame, of a screen mountedin a chamber in the sill, an L-shaped plate secured to the upper end ofthe screen, and provided with an opening, and a bail provided with anoperating-pin to extend through said opening permitting the bail toengage the under side of the horizontal member of the plate securing itto the sash.

2. The combination with a sash and frame, of a screen mounted on theframe, a bail provided with an operating-pin and constructed of a singlepiece of resilient material having its ends bent at right angles, meansfor se curing the bail to the sash, and means carried by the screen tobe clamped, by the bail, securing the screen to the sash.

3. The combination with a window sash and frame, of a screen mounted ina chamber in the sill, an L-shaped connecting-plate secured to the upperend of the screen and provided With a central opening, a bail providedwith an operating-pin and constructed of a single piece of resilientmaterial having its ends bent at right angles and perforated, and meansfor securing said bail to the sash.

In testimony whereof I afiix my signature in presence of two witnesses.

HENRY D. MILLS.
